The union made major concessions in 2007, however the Bush loan deal requires GM to get the union to agree to renegotiate a promised $21 billion company contribution to a retiree trust fund that will be the UAW, and also to force the union to agree to accept wage and work conditions equal to those at non-union plants.

The union has raised loud objections to the terms of the loan, and a bill being pushed by Democrats in the House would strip the loan of these forced concessions.
